Easy passing data to views

Submitted by iraitc - 1 year ago

This Trait helps you to pass "variables" anywhere in controllers to "view" . you can use "$this->view->..." in controller to pass your variables , also you can use "$this->view()" same as "view()" helper with same functionality to render the view . ( this package is made by larabook.ir)

<?php
 /*
 
usage in controllers : 

class HomeController extends Controller
{
use EasyViewLoader;

public function home()
    {

        $this->view->with(['var1'=>'will be deleted']);

        $this->view->with('name', ['hamed', 'mehrsa']);
        $this->view->withFamily('pakdaman');
        $this->view->gender = 'Male';

        $site = 'www.larabook.ir';

        if (isset($this->view->var1))
            unset($this->view->var1);

        // get all variables will pass to view
        print_r($this->view->getData()); 
        
        return $this->view('homepage', compact('site'))->withErrors('some errors')->withSuccess('some ...'); '
        // instade of using view() helper
    }
}
